Texas police and Humane Society officials seized more than 600 dogs and about 15 cats Tuesday in a raid on what they say is a puppy mill in Kaufman County, MyFOXDFW reported.
The Humane Society began investigating the kennel when someone came to them inquiring about dog food donations for the operation. Authorities found poor living conditions and sickly animals when they visited the location.
Sheriff's deputies said the kennel's owners have not yet been arrested or charged.
The kennel operated in a large metal building in a rural area near the Prairieville community, about 45 miles southwest of Dallas.
The animals seized are mostly Chihuahuas, poodles and other small-breed dogs. They were examined by vets to determine which ones needed medical attention.
